Product details

It operates at 50 Hz and carries an insulation voltage (Ui) of 460 V. The 300 mA sensitivity means it's sized for whole-circuit earth-leakage protection rather than individual equipment; Type A handles pulsating DC fault currents that a plain AC type would miss.

At 40 °C the unit carries 58.6 A; at 55 °C it's 54.81 A; at 70 °C it drops to 50.4 A. The body is 3 modular-width units wide (107 mm), 70 mm deep, 90 mm tall, and mounts in any position. IP20 only when the distribution board is installed with connected conductors — not a standalone open-panel part.

Surge current resistance is 1 kA. No UL, CSA, or CE marks are listed in the spec record — verify local acceptance before specifying into a UL 508A panel.

Frequently asked questions

Where can I buy 5SM2635-6 and how do I get a price?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is 5SM2635-6's listed depth and width?

Depth is 70 mm, width is 107 mm (3 modular-width units), height is 90 mm.

What residual current type and sensitivity does 5SM2635-6 use?

Type A residual current detection with a 300 mA rated fault current — suitable for pulsating DC fault currents from electronics or variable-speed drives.
