The E-T-A 412-K14-LN2-7.5A is a single-pole, high-performance thermal circuit breaker featuring a tease-free, trip-free, snap-action mechanism with manual push/pull ON/OFF actuation. It is designed for panel mounting and includes an indicator band on the push button to clearly show the tripped/off position.
This circuit breaker has a current rating of 7.5A and is suitable for extra-low voltage wiring systems. It supports a DC voltage rating of 28V and an AC voltage rating of 115V at 400 Hz. The operating temperature range is from -55°C to +75°C.
Typical applications include extra-low voltage wiring systems on all types of vehicles for land, sea, and air, as well as defence equipment and battery-powered machines. The breaker offers an interrupting capacity of 6,000A at both Icn and UL 1077 standards. It has a degree of protection of IP40 in the operating area and IP00 at the terminals.
Environmental testing includes vibration resistance up to 10g, shock resistance of 25g, 96-hour corrosion resistance, and 240-hour humidity resistance. The typical life is rated for 4,000 operations at 2 times the rated current.
The breaker is rated for 28 VDC and 115 VAC (400 Hz).
It is designed for panel mounting with a push-pull plunger actuator.
