This E-T-A 447-S-H-FN-225A is a single-pole, thermal-magnetic circuit breaker with a robust chassis mount design. It is rated for 225 Amperes and operates at a DC voltage of 28 Volts.
The breaker offers a high interrupting capacity of 10,000 A and is built to withstand demanding environmental conditions, including a wide ambient temperature range of -55 to +75 °C. Its construction meets stringent standards for vibration, shock, corrosion, and humidity resistance.
Key electrical specifications include an insulation withstand voltage of 1.5 kV and dielectric strength of 1,000 V AC for both the operating area and main to auxiliary contacts. The insulation resistance is rated above 100 MΩ at DC 500 V.
Designed for reliable protection, this circuit breaker is suitable for applications requiring robust thermal-magnetic tripping characteristics and a compact, surface-mounted form factor. The actuator type is push-to-reset.
