Product details

The 6 A rating is at 30 °C; above that, derate to 5.5 A at 40 °C, 5.3 A at 45 °C, 5.1 A at 50 °C, 4.8 A at 55 °C, and 4.5 A at 60 °C. If the panel ambient runs 50 °C, size the load to 5.1 A, not 6 A. The 880 V DC maximum rating covers series-string DC bus voltages common in solar, UPS, or traction battery systems.

Deployment context

Rated for residential buildings and infrastructure — think DC distribution in telecom shelters, solar combiner boxes, or battery banks. Mount in any position; the sealable cover allows locking against unauthorized operation.

Frequently asked questions

Where can I buy 5SL5406-7RC and how do I get a price?

The part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the closest functional second-source to 5SL5406-7RC?

The 5SL3640-7MB is a 4-pole AC miniature circuit breaker (400 V AC, 40 A, C characteristic) in the same SENTRON 5SL family and identical footprint (76 mm depth, 72 mm width, 90 mm height). It is not a direct DC substitute — the 5SL5406-7RC is the DC-rated variant for 880 V DC systems.

What compliance documentation does this brand provide for 5SL5406-7RC?

The part is halogen-free and silicon-free. The manufacturer provides standard declarations of conformity (CE, UKCA) and material compliance (RoHS, REACH) upon request through the RFQ process.
