Overview
The E-T-A 3120-F323-P7T1-W12DB4 is a compact thermal circuit breaker/switch combination that integrates an ON/OFF control switch with integral overcurrent protection. Designed as an ON/OFF switch with integral overcurrent protection (S-type TO CBE to EN/IEC 60934), this unit provides reliable resettable protection in a single package.
Key Features
- Bimetal trip element for automatic overcurrent protection
- Flange-mounted snap-in design with 9mm collar height for standard 50.5 x 21.5 mm cut-out mounting
- 2 thermally protected poles with blade terminals and rocker actuator style
- Suitable for AC and DC current applications
- Manual reset capability for operator control
- Also available as switch-only version in accordance with IEC/EN 61058
Technical Specifications
Ideally suited for overload protection of motors, pumps, transformers and cables. The thermal response characteristics provide temperature-dependent trip behavior to minimize nuisance tripping in variable ambient conditions. Terminal receptacles feature 6.3 mm width dimensions in accordance with DIN 46340 part 3, shape A.
Typical Applications
- Motor and pump protection in industrial equipment
- Transformer overcurrent protection
- Cable and wiring circuit protection
- Low-voltage electrical system protection
- Machinery and industrial automation control circuits
