TeSys GB Thermal-magnetic circuit breakers for auxiliary circuits

Introduction

Introduction
PB110899_20.eps PB110901_20.eps GB2 thermal-magnetic circuit breakers protect and isolate the control circuits of

industrial equipment with contactor coils, transformers.…
They protect and isolate single-phase auxiliary circuits such as solenoid valves,
electro-brakes, battery chargers, supplied from the control circuit voltage.

GB2CB, GB2CD, GB2DB
12 ratings are available, from 0.5 to 20 A, in single-pole (GB2CB), single-pole +
neutral (GB2CD) and 2-pole (GB2DB) versions.
They have a magnetic tripping threshold set at between 12 and 16 In to withstand the
current peaks generated by many industrial components.

GB2CS
2 ratings are available, 0.5 and 1 A, in single-pole version.
GB2CB GB2CD The magnetic tripping threshold is set between 5 and 7 In.

Functions, installation
PB110902_20.eps PB110900_20.eps Clip-on fixing onto all types of 35 mm 5 rails, on 4 rails and on Telequick
mounting plates.
Upstream and downstream marking by means of AB1 clip-in markers.
Clear indication of “I” and “O” positions on the operator.
Tamper-proof device which requires no special maintenance (fixed magnetic and
thermal tripping thresholds).

Selection for the protection of circuits supplied by transformers
Single-phase transformers.
Magnetising peak: 20 In.
Operation of magnetic trips: 13 In.
