This E-T-A 8340-T120-K1M2-ALH0-50A is a single, two, or three-pole magnetic and hydraulic-magnetic circuit breaker with a trip-free mechanism and toggle actuation. It offers a choice of fast magnetic only or hydraulically delayed switching characteristics, making it suitable for a wide range of applications including power supplies, control equipment, communication systems, and EDP systems.
Key electrical specifications include a voltage rating of 250V AC and 80V DC, with a current rating range of 0.02 to 50A DC and 0.02 to 30A AC. The breaker has an interrupting capacity of 6 x IN at AC and 4 x IN at DC. It operates within an ambient temperature range of -40 to 85°C and features a degree of protection of IP40 for the operating area and IP20 for the terminal area.
The circuit breaker is designed for DIN rail mounting and has a combi-foot design for symmetric rail mounting. It is approved to CBE standard EN 60934 (IEC 60934) and UL1077 standards. The typical life is rated at 6,000 operations at 1 x IN inductive and 10,000 operations at 1 x IN resistive.
Environmental considerations include resistance to vibration up to 10g and shock up to 100g. It also has corrosion resistance for 96 hours and humidity resistance for 240 hours. The mass is approximately 98g per pole.
