Product details

For selective coordination upstream, the fuse backup limits are gL/gG 25 A at 400 V and 500 V, and gL/gG 20 A at 690 V. Motor full-load current equivalents: 0.13 hp at 230 V, 1 hp at 460/480 V, and 1 hp at 575/600 V. The 3RV2311-1BC20 is rated for AC-3 switching duty at 15 operations per hour maximum, same for AC-3e. That rate suits intermittent motor starting — not continuous jogging or high-cycle applications.

Panel integration and clearances

Mounting position is any orientation. Required free space around the device: 50 mm upward, 50 mm downward, 30 mm to the side, zero forward or backward clearance needed. That means it can sit flush against the backpanel or enclosure wall.

Frequently asked questions

What compliance documentation does this brand provide for 3RV2311-1BC20 (RoHS, REACH, UL, IEC)?

Siemens SIRIUS products typically carry UL, CSA, CE, and IEC certifications. RoHS and REACH declarations are available from Siemens documentation. Specific certs for this order code should be confirmed at time of order.
