Product details

The Siemens SENTRON 5SM3311-6KL is a 2-pole residual current operated circuit breaker (RCCB), Type A, rated at 16 A and 30 mA residual trip current for 230 V AC systems, with neutral on the left side of the unit. Rated for 50 Hz, it snaps onto a DIN rail (REG) and occupies 2 width units (36 mm), with a depth of 70 mm and height of 90 mm — standard panel footprint for a 2-pole residual current device.

Installation and wiring notes

Terminals accept solid or stranded conductors from 1 mm² up to 16 mm², with a tightening torque of 2.5 to 3 N·m — spring-cage or screw terminals? The spec says screw-type, so use a torque screwdriver to avoid terminal damage. Silicon-free construction matters for applications where silicone outgassing could contaminate contacts or optics.

Frequently asked questions

How do I get current pricing and availability for 5SM3311-6KL?

Submit an RFQ through this listing. The part is sourced to order through independent distribution; pricing and stock levels are confirmed at quote time.

What is 5SM3311-6KL's listed depth?

The depth is 70 mm, with an installation depth also listed at 70 mm — it sits flush against the DIN rail without extra clearance behind the panel.

What conductor sizes does 5SM3311-6KL accept?

Solid and stranded conductors from 1 mm² up to 16 mm², terminated with screw-type terminals torqued to 2.5–3 N·m.

Will 5SM3311-6KL drop into a panel specified around 5SL6550-7BB without rewiring?

The 5SL6550-7BB is a miniature circuit breaker (MCB), not an RCCB — different function, different wiring. The 5SM3311-6KL is a residual current device and requires its own dedicated circuit position; it cannot simply replace an MCB without reconfiguring the circuit.
