Product details

The adjustable overload release is set for 2.8...4 A, and the magnetic short-circuit release trips at 52 A. At 400 V AC-3 duty it switches 4 A, corresponding to a 1.5 kW motor — that's the rating that decides the motor size it protects, not the raw thermal current.

Clearance: 20 mm above and below, 9 mm at the sides, zero forward or backward — so it sits flush against the backpanel. IP20 finger-safe front per IEC 60529, meaning the busbars are protected from accidental contact in an open panel.

RoHS compliant per the substance prohibition date of 01.01.2013. The front face is finger-safe to IP20 per IEC 60529.

Frequently asked questions

Where can I buy 3RV1011-1EA10-ZI45 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the difference between 3RV1011-1EA10-ZI45 and 3RV1011-1HA10?

The 3RV1011-1HA10 is the same SIRIUS S00 motor protection breaker but with a higher adjustable overload range of 5.5...8 A and a 52 A magnetic release, rated for 8 A AC-3 at 400 V (2 hp at 460/480 V). The -1EA10 covers 2.8...4 A (1.5 kW at 400 V). Both share the same footprint, DIN rail mount, screw terminals, and Class 10 trip — so the -1HA10 drops into the same panel without rewiring if the motor load is larger.

What does the 20 mm upwards clearance mean for panel layout?

The 20 mm upwards and 20 mm downwards clearance is the minimum free air space required above and below the breaker for proper heat dissipation and arc quenching. The 9 mm side clearance is the minimum to adjacent devices. Zero forward or backward clearance means it can sit directly against the backpanel and enclosure door.
