Introduction
Chapter 1 INTRODUCTION
The Eurotherm 451-455-461 thyristor unit range offer a vast number of possibilities which,
for the most part, meet the requirements of the low and medium power market. The current
range is from 15 A to 150 A for voltages of up to 660 V rms.
The range is divided into two main groups:
•Solid state contactors (451 series)
The thyristor units, driven by a logic signal, operating in ON/OFF mode with tiring of
the thyristors when the supply voltage changes to zero.
•Power units (455 and 461 series)
The thyristor units driven by an analogue signal emit an output signal proportional
to the thyristor firing angle and burst firing input signal, or a combination of both
signals.
Thyristor unit voltage selection
•Single-phase power supply from 100 to 240 V:
Nominal voltage of unit 240 V.
•Single-phase power supply from 380 to 415 V:
Nominal voltage of unit 440 V.
•Three-phase power supply, mounting 3 wires plus neutral:
Nominal voltage of unit: take into account the voltage between phase and neutral.
•Three-phase power supply, mounting 3 wires (star or delta) or
6wires (open delta):
Nominal voltage of unit: take into account the voltage between phases.

Introduction
451 series (models 451 to 454)
Three sorts of isolated logic input are available:
•The standard input is suitable for all control signals for solid state contactors,
generated by the Eurotherm controllers.
•The TTL input, available as an option, allows greater sensitivity, without
increasing the current consumption. This input can be driven by a standard
TTL logic.
•The "multi-input", available as an option, is used when several units
must be driven by the same logic signal, and with a minimum current
consumption.
The 451 series can be equipped with a partial load failure detection.
455 series (models 455 to 458)
The input signal and thyristor firing mode configurations are set at order and cannot be
changed (soldered bridge configuration).
The 455 series has a "Slave" output and an inhibition function.
461 series (models 461 to 464)
The input signal and thyristor firing mode configurations are easy to modify by the user
with configuration mini-switches.
The 461 series has current limit, partial load failure detection, gating (except on the 461
model), inhibition functions and the "Slave" output.

2.1 GENERAL INFORMATION COMMON TO THE 3 SERIES
.Supply voltage : +10 % -15 % of the nominal voltage
.Residual load current in locked status : <30 mA
Heat dissipation
Each unit dissipates a maximum of 1.3 W per amp issued.
This dissipation induces a rise in the ambient temperature if the units are mounted in
cabinets.
It is essential to check that the external ambient temperature of the cabinet does not
exceed 50°. Otherwise, provide a fan cooling system.
If this system includes dust removal filters, systematically perform a preventive
cleaning operation every 3 or 6 months depending on the degree of pollution.
Operating temperature: 0°C to 50°C with radiator in vertical position
Storage temperature: -10°C to + 70°C.
Unit cooling
The heat dissipation of the thyristors induces an overheating of the heatsink on which
they are mounted.
Two types of cooling are provided:
- by convection cooling 7 V 4 c o,t, 7/ S4- - CL-
- by fan cooling. 3 / 4 copvlu,61/0 7,C,V
• 15 to 75 A nominal units:
cooling by convection cooling.
•100 to 150 Anominal units:
cooling by fan cooling.
In this case, the unit is equipped with a temperature safety switch which inhibits
thyristor firing in the event of overheating.

2.2 PARTIAL LOAD FAILURE DETECTION
Partial load failure detection exists as an option for the 451 series and comes as
standard for the 461 series.
•Partial load failure (PLF) detection principle:
comparison of the load current and voltage (451 series) or
of the power supply (461 series)
to detect an increase in impedance.
•Improved 20% discrimination of the current in the load, does not depend
on supply voltage variations.
•Setting: with a potentiometer on the front fascia from 10 to 100 % of
the unit's nominal current.
•Indication on front fascia with an LED.
•PLF output made via relay switch.

Specifications
For assembly:
•tilt the module approximately 20 degrees forwards in relation to the horizontal
•insert the rotation rod in the baseplate recipient (see fig. 2.1)
•raise the module to the horizontal
•turn the lock by a quarter-turn.
The minimum space between 2 modules side by side must be at least 20 mm.
If the modules are mounted on top of each other, it is essential to leave a vertical space of at
least 80 mm between 2 modules, in order to guarantee good ventilation.
For installations in fan-cooled cabinets, it is recommended to fit a fan failure detection device.
For disassembly:
• unlock the top attachment by a quarter-turn
•tilt the module approximately 20 degrees forwards in relation to the horizontal
•release the module from its baseplate.
Warning
Before disassembling the module, make
sure that the heatsink is not hot.

2.5 INTERNAL HIGH SPEED FUSE REPLACEMENT
The 451 series static contactors and the 455 and 461 series power units (nominal currents
from 15 to 125 A) are equipped with internal high speed fuses.
They are fitted at the rear of the pull-out module.
For the 150 A nominal current, the high speed fuse and its support are external and
driven separately from the thyristor unit.
Important
The high speed fuses are only used to protect the thyristors against
over-loads of wide amplitudes.
The user's installation must be protected (non-high speed fuses,
thermal, magnetic or electromagnetic circuit breaker, suitable
isolating switch) and comply with applicable standards.
In the event of blow-out of the internal fuse, a red indicator light on the front panel of
the unit lights up (except for the 150 A nominal unit).
The fuse can be accessed via the rear of the module.
To replace the fuse:
• pull out the module from its baseplate
•unfasten the 2 fuse attachment screws
•fit the suitable fuse (the references of which are given in the
table overleaf).
