Product details

The D-curve trips between 10 and 20 times rated current — that's the headroom you need for motor inrush without nuisance trips. At 400 V AC (multi-phase) or 440 V AC (single-phase), it covers standard industrial supply voltages across 50/60 Hz.

At 72 mm wide (4 modules) and 76 mm deep, it fits standard 35 mm DIN rail enclosures. Installation depth of 70 mm leaves clearance behind the DIN rail for wiring. IP20 with connected conductors is the protection class, so it's meant for enclosed panels, not open washdown areas. The sealable option (padlockable toggle) lets you lock out a circuit for LOTO procedures.

Frequently asked questions

What are the key ratings for the 5SY4616-8?

It's a 4-pole (3P+N) D-curve MCB rated 10 kA per EN 60898 and 20 kA per IEC 60947-2 at 400 V AC, with a DC breaking capacity of 15 kA at 60 V.

Where can I buy the 5SY4616-8 and get current pricing?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What compliance standards does the 5SY4616-8 meet?

It complies with IEC/EN 60898-1, IEC/EN 60947-2, and UL1077. It is also halogen-free and silicon-free.

Will the 5SY4616-8 drop into a panel specified for a similar 4-pole MCB?

Yes, at 72 mm wide (4 modular units) on standard DIN rail, it fits the same footprint as other 4-pole SENTRON breakers. The combined terminals accept busbar or wire without modification.
