Siemens SENTRON 5SY4502-7 Miniature Circuit Breaker 4-Pole C 2A 400V 10kA

The Siemens 5SY4502-7 stands out as a 4-pole miniature circuit breaker with C tripping characteristic and a low 2 A rated current, ideal for protecting sensitive control circuits where precise overload discrimination is required. Its 10 kA switching capacity and current-limiting class 3 ensure reliable interruption of short-circuit currents in industrial and building installations.

Highlights

• 4-pole MCB from the SENTRON series, type C, rated current 2 A
• Rated voltage 400 V AC, 50/60 Hz, with 10 kA switching capacity
• DIN rail mounting, screw terminals for conductors up to 35 mm² solid
• IP20 protection at terminals, IP40 with cover installed
• Ambient operating temperature range -25 °C to +45 °C

In daily use

This breaker is suited for distribution boards and control panels where space is limited but four-pole switching is needed. The C characteristic allows for moderate inrush currents, making it appropriate for lighting circuits, small motors, and control transformers. Its mechanical endurance of 20,000 switching cycles and electrical endurance of 10,000 cycles ensure long service life even with frequent operation.
