Siemens 5SJ41408HG41 Miniature Circuit Breaker 40 A (1 Pole)

Product Description

Siemens 5SJ41408HG41 is a single-pole miniature circuit breaker rated 40 A and 240 V with a D trip characteristic and 10 kA interrupting capacity. The device complies with UL 489 and has a depth dimension D = 70 mm. It is intended for branch circuit protection and for applications with higher inrush currents where a D-trip characteristic is required.

• Single-pole D-trip miniature circuit breaker, 40 A rating, 240 V, 10 kA interrupting capacity, UL 489 listed
• Compact dimensions 18 x 110 x 70 mm (D = 70 mm) with 35 mm DIN-rail mounting and IP20 enclosure
• Line/load screw connections accepting 14 to 4 AWG copper conductors; thermal/magnetic trip suitable for high inrush loads

Product Highlights

Single-pole 40 A D-trip MCB for 240 V systems with 10 kA interrupting capacity and DIN-rail mounting
