Product details

It is rated for 400 V AC at 50/60 Hz, and carries a UL 1077 / CSA C22.2 No.235 rating of 5 kA. The 3-pole design switches all three phases simultaneously; there is no neutral pole (neutral conductor switching is not provided).

Environmental and compliance details

The housing is sealable (can be locked in the OFF position for lockout/tagout). Operating temperature range is -40 °C to 75 °C, with humidity derating above 55 °C: max 95% RH at 55 °C, tapering to 35% RH at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz.

Installation and integration notes

Combined terminals at both top and bottom accept the same conductor size, simplifying wiring. The supply cord can enter from any direction. The 3 MW width (54 mm) matches the standard DIN-rail footprint; verify that the adjacent devices leave enough space for the handle to toggle freely and for the sealable cover to engage.

Frequently asked questions

How do I get current pricing and availability for 5SY6325-7CC?

Pricing and availability are confirmed at quote time against an RFQ. Submit a request through the storefront for a current quote.

What is 5SY6325-7CC's listed depth (76 mm) on this component line?
