The Phoenix Contact ECP 3 (part number 0911047) is a 24V DC electronic circuit breaker with a 3A nominal current rating. It offers selective load protection with electrical isolation, crucial for applications using switched-mode power supplies where an overload in one circuit should not affect others.
This circuit breaker utilizes active electronic current limitation, typically restricting current to 1.8 times the nominal current during switch-on of capacitive loads up to 20,000 µF and in overload or short-circuit conditions. It provides safe overload shutdown from 1.1 times the nominal current, even with long load cables or low cable cross-sections. The device features an electronic shutdown characteristic curve and a manual on/off push-button.
With a design width of just 12.5 mm per channel, it is suitable for space-constrained applications. The ECP 3 can be plugged onto a modular base for quick and easy mounting. It indicates operating and error states via an LED and integrated signal contacts.
Key specifications include a 24V voltage rating, 3A current rating, and a single pole design. The mounting type is panel mount. This solid-state breaker is designed for reliable protection of DC load circuits.
