Protection Features

The Schneider BIK 114 combines thermal and magnetic trip mechanisms in one unit. A bimetallic strip responds to sustained overloads by opening the circuit slowly. A magnetic coil reacts to short-circuit currents within a few milliseconds. Consequently, this breaker protects both equipment and personnel effectively.

Trip Curve Characteristics

This C-curve breaker suits inductive loads like motors, solenoids, and transformers. Thermal protection activates between 1.13 and 1.45 times the rated current. Magnetic protection triggers between 5 and 10 times the rated current instantly. Therefore, the breaker allows normal inrush currents without nuisance tripping.

Installation and Mounting

Mount this breaker on standard 35 mm DIN rail inside a control cabinet. You can install it in any orientation without affecting the trip performance. For best results, leave 20 mm of clearance above and below the unit. The 4-pole design allows switching three phases plus neutral or auxiliary circuits.

Terminal and Wiring Information

Box-type screw terminals accept copper wires from 1 to 25 square millimeters. You must strip 12 mm of insulation before inserting the wire into the terminal. Tighten each screw to a torque of 2.0 Nm (17.7 lb-in). Use ring or fork terminals for stranded wire applications.

Visual Status Indication

A red indicator flag in the handle window shows the breaker’s tripped status. When tripped, the handle moves to a central position between ON and OFF. You must push the handle to OFF before resetting it to ON. Therefore, operators know immediately when a fault has occurred.

Interrupting Capacity

This unit can interrupt 10,000 Amps of fault current at 400 VAC safely. It meets IEC 60898 and 60947-2 standards for industrial applications. The arc chamber extinguishes the electrical arc within half a cycle. Consequently, this breaker limits the let-through energy during short circuits.

Why Choose This Breaker

This genuine Schneider breaker guarantees correct trip curves for machine protection. Generic breakers may have different characteristics that cause nuisance trips. Therefore, choose this original component for reliable overcurrent protection in your panels.
