Product details

Breaking capacity and derating

At DC per IEC 60947-2 the breaker is rated 15 kA; under UL 1077 / CSA C22.2 No.235 it carries 5 kA. Temperature derating is published: 13 A at 45 °C, 12.68 A at 50 °C, 12.34 A at 55 °C. The surrounding humidity influence is also specified — max 95% RH up to 55 °C, tapering to 35% RH at 75 °C — so the breaker is usable in unconditioned enclosures as long as the ambient profile is checked against the curve.

Rated IP20 with connected conductors (finger-safe when installed in a panel). Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Halogen-free and silicon-free construction, sealable, with touch protection and combined top/bottom terminals. Neutral conductor switching is integrated.

Frequently asked questions

How do I get pricing and availability for 5SY8613-7?

The 5SY8613-7 is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.

What is the closest functional second-source for 5SY8613-7?

The 5SY4140-7 is a peer from the same SENTRON family, but it is a different pole/current variant. The 5SY8613-7 is a 4-pole C-curve breaker; the 5SY4140-7 is a 4-pole B-curve unit. They share the same 4-module DIN footprint and 400 V AC rating, so the 5SY4140-7 will physically fit the same panel position, but the tripping curve differs — verify coordination before substituting.
