## Summary description

EATON 133103 is an auxiliary contact block designed as an accessory for compatible circuit breakers. It provides additional signaling and control contacts to integrate breakers into control and monitoring circuits, enabling remote indication of breaker status and automation functions. Suitable for use in industrial and commercial electrical panels to expand functionality and improve system monitoring.

## Long description

EATON 133103 auxiliary contact block is an accessory for compatible circuit breakers that provides additional signaling and control contacts. It enables remote indication of the breaker position and integration into automation or monitoring circuits. The compact contact block mounts to the breaker body and extends functionality without altering the breaker’s primary protection characteristics, making it useful in industrial and commercial electrical panels where status feedback and interlocking are required.
Advantages
The auxiliary contact block offers reliable mechanical and electrical interfaces for breaker status signaling, designed to respond directly to the breaker’s trip and switch positions. Its compact construction conserves panel space while delivering extra contacts for control circuits. Installation does not change the breaker’s protective performance, and the block provides consistent switching behavior suitable for repetitive monitoring and control operations.
Suitable for
 Remote indication of breaker ON/OFF/tripped status in control rooms
 Integration with PLCs, SCADA and building management systems for automated monitoring
 Interlock circuits and control logic within distribution and motor control centers
 Retrofitting existing panels to add signaling without replacing breakers
Key specifications
 Function: auxiliary contacts for status signaling and control
 Mounting: accessory attachment to compatible circuit breakers
 Contact type: mechanical changeover/contact switching synchronized with breaker mechanism
 Construction: compact housing suitable for panel installation
 Intended environment: industrial and commercial electrical panels
How to use
Mount the auxiliary contact block onto a compatible circuit breaker according to the breaker manufacturer’s mechanical and electrical instructions. Connect the contact terminals to the control or monitoring wiring routed to relays, PLC inputs, alarm circuits or indicator lights. Ensure all power is isolated before making connections and verify that the block engages correctly with the breaker mechanism so that contact position corresponds to breaker ON, OFF and tripped states. After installation, perform functional tests by operating the breaker and confirming correct signaling to the monitoring equipment.
Usage recommendations
Use the auxiliary contact block only with circuit breakers and mounting arrangements specified by the breaker manufacturer. Observe rated voltages and current limits for signaling circuits, and follow local electrical codes and safety procedures during installation and maintenance. Periodically inspect contact integrity and wiring connections as part of routine panel maintenance.
