Product details

What this MCB does on the panel

The Siemens 5SY4416-7CV is a 4-pole miniature circuit breaker with a C-curve tripping characteristic, rated 16 A at 35 °C and 440 V AC multi-phase.

Mounting and fit

Occupies 4 modular width units (72 mm wide, 90 mm tall, 76 mm deep, 70 mm installation depth). Combined terminals top and bottom — spring-cage or screw, accepts the usual panel wiring. IP20 with conductors connected; sealable if the panel spec requires it.

Thermal derating — the real-world current

Rated 16 A at 35 °C, but the current drops as ambient rises: 15.12 A at 40 °C, 14.66 A at 45 °C, 14.2 A at 50 °C, 13.68 A at 55 °C. That's the number to use for the BOM, not the 35 °C figure.

Frequently asked questions

What is the breaking capacity of 5SY4416-7CV?

15 kA rated breaking capacity per IEC 60947-2 at 440 V AC multi-phase.

Will 5SY4416-7CV drop into a panel specified for 5SY4316-7CV?

Both are 4-pole C-curve MCBs in the same 5SY family with identical 72 mm width and 4 MW footprint, so mechanical fit is the same. The difference is the current rating — 5SY4416-7CV is 16 A, while 5SY4316-7CV is 16 A as well (same rating). Check the peer's exact rating before swapping; if it's a different amp rating, the thermal derating curve changes.
