Product details

Siemens SENTRON 5SL3316-7MB — 3-pole C-curve MCB, 16 A, 400 V

The Siemens 5SL3316-7MB is a SENTRON miniature circuit breaker (MCB) rated 16 A at 400 V AC with a C tripping characteristic and a 4.5 kA breaking capacity per EN 60898.

At 16 A rated current (at 30 °C ambient), it carries 3.68 kW per pole on a 230/400 V system. The IP20 rating applies only with connected conductors, so the front terminals are finger-safe but the busbar area is not.

DIN-rail integration and footprint

At 54 mm wide (3 modular units), 76 mm deep, and 90 mm tall, the 5SL3316-7MB clips onto a standard 35 mm DIN rail.

Frequently asked questions

Where can I buy the 5SL3316-7MB and get a price?

The 5SL3316-7MB is sourced and quoted to order against an RFQ through our independent distribution network. Submit a request for quote (RFQ) to confirm current availability and pricing.

What is the breaking capacity of the 5SL3316-7MB?

The breaking capacity is 4.5 kA at 400 V AC per EN 60898. This is the standard interrupting rating for this class of MCB in residential and infrastructure panels.

What is the width of the 5SL3316-7MB in modular units?

The 5SL3316-7MB occupies 3 modular width units, which is 54 mm on a standard DIN rail. This is the standard width for a 3-pole MCB in the SENTRON range.
