The Phoenix Contact 0915470 is a single-pole thermal magnetic circuit breaker designed for reliable overcurrent protection in industrial control panels. Rated for a nominal current of 20A, it supports operation at 250V AC or 65V DC with a rated surge voltage of 4kV. The device utilizes a thermal-magnetic tripping mechanism to handle both sustained overloads and sudden short circuits.
Engineered for ease of installation, this breaker mounts securely on standard NS 32, NS 35/15, or NS 35/7.5 DIN rails. It employs a screw connection method with a tightening torque range of 0.6 to 0.8 Nm, accommodating solid conductors up to 6mm² and stranded wires up to 4mm². The unit measures 12.5mm in width and features a black polyamide (PA-F) housing that meets UL 94 V0 flammability standards.
Operating within an ambient temperature range of -30°C to 60°C, the 0915470 is suitable for diverse environmental conditions classified under Pollution Degree 3 and Surge Voltage Category III. Its compact form factor and robust electrical ratings make it an ideal choice for safeguarding sensitive equipment in automation systems, power distribution networks, and machinery control circuits.
