PS-ETIMAT 10 (1NC) — an auxiliary contact for ETIMAT series circuit breakers, which provides status signaling from the circuit breaker to a monitoring or automation system. The 1NC (normally closed) configuration means that the contact is closed in the idle state and opens when the circuit breaker trips or is de-energized.
Technical advantages
- Status signaling: indicates when the circuit breaker trips or is de-energized.
- Compatibility: installs on the left side of ETIMAT circuit breakers without tools.
- Compact design: the modular width allows for efficient use of space in the panel.
- Reliability: made of heat-resistant materials that withstand mechanical stress.
- Versatility: suitable for use with dispatch systems, PLCs, and SCADA.
Features
The 1NC contact block operates on the principle of a normally closed circuit: when the circuit breaker is in the on position, the circuit is closed; when the circuit breaker trips or the protection is activated, the circuit opens. This allows for easy integration into emergency alarm or remote control circuits.
The module is mounted directly on the side of the ETIMAT circuit breaker, secured without additional tools, and connected via screw terminals.
Applications
The PS-ETIMAT 10 (1NC) is used for:
- Transmitting the “circuit breaker tripped” signal to the control system.
- Implementing equipment interlock circuits during power outages.
- Integration into ATS (automatic transfer switch).
- Monitoring the status of protective devices in industrial and commercial switchboards.
