Product details

Siemens SENTRON 5SM2647-0 RCD unit, 4-pole, 100 A, 300 mA

The Siemens SENTRON 5SM2647-0 is a 4-pole residual current device (RCD) of type AC, rated for 100 A continuous current and 300 mA fault sensitivity at 400 V AC, 50 Hz. This RCD mounts in a SENTRON distribution board, occupying 5 modular width units (roughly 90 mm of DIN-rail space).

Sourcing and lifecycle — active, quoted to order

The part belongs to the SENTRON family of protection devices, used across residential, commercial, and industrial distribution. No official successor or replacement has been published; the 5SM2647-0 remains the current order code for a 4-pole 100 A/300 mA Type AC RCD in the 5SP4 system.

Frequently asked questions

What are the key ratings of the 5SM2647-0?

The 5SM2647-0 is a 4-pole Type AC RCD rated at 100 A continuous current, 300 mA fault sensitivity, 400 V AC operating voltage, and 50 Hz frequency. It has an instantaneous trip characteristic with no adjustable time delay, and occupies 5 modular width units on a DIN rail.

Where can I buy the 5SM2647-0?

The 5SM2647-0 is sourced and quoted to order against an RFQ through independent industrial automation distribution. Availability and current pricing are confirmed at quote time — submit an RFQ to receive a firm offer.

What is the 5SM2647-0 used for?

This RCD provides earth leakage protection for 3-phase 4-wire circuits up to 100 A in SENTRON distribution boards. The 300 mA sensitivity makes it suitable for fire protection or equipment protection on main or sub-main circuits in commercial and industrial installations.
