Product details

The Siemens SENTRON 5SL6316-7BB is a 3-pole miniature circuit breaker rated 16 A with a C tripping characteristic, designed for 400 V AC multi-phase operation at 50/60 Hz. Its breaking capacity is 6 kA per both EN 60898 and IEC 60947-2, which means it safely interrupts short-circuit faults up to 6 kA without upstream device coordination issues in residential and infrastructure panels.

Occupying 3 modular width units (54 mm) on a DIN rail, the breaker mounts in any position with an installation depth of 70 mm and overall depth of 76 mm. The IP20 rating applies with connected conductors, so the front face is touch-safe once wired; no additional finger-duct cover is required for standard panel builds.

Frequently asked questions

Where can I buy 5SL6316-7BB and get a price?

This part is sourced and quoted to order against an RFQ through our independent distribution network. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial response.

Will 5SL6316-7BB drop into a panel specified for 5SL4363-7 without rewiring?

Yes, the two breakers share identical dimensions (76 mm depth, 54 mm width, 90 mm height), mounting position flexibility, and the same 3-pole C-curve footprint. The key difference is breaking capacity: 5SL4363-7 is rated 10 kA versus 6 kA for this unit. If the panel's fault level is below 6 kA, the swap is mechanical and electrical drop-in.

What compliance documentation does Siemens provide for 5SL6316-7BB?

The breaker carries IEC/EN 60898-1 and IEC 60947-2 ratings, is halogen-free and silicon-free, and is designed for overvoltage category III / pollution degree 2. Standard Siemens declarations of conformity (CE, UKCA) and material compliance (RoHS, REACH) are available on request.
