Description
Three-pole circuit breaker AE 2046M-100-00U3 (25A, UKHL4)
The AE 2046M series industrial three-pole circuit breaker (version 100-00U3) with a rated current of 25 A is designed for conducting current in normal mode, as well as for automatic disconnection of electrical circuits during short circuits, overloads, and unacceptable voltage drops. It is manufactured in a durable carbolite housing and is widely used in distribution boards, main distribution boards (VRU), and for the protection of asynchronous electric motors.
Key Advantages and Features:
- Combined Protection: Equipped with a thermal release for protection against prolonged current overloads and an electromagnetic release for instantaneous disconnection during short-circuit (SC) currents.
- Durable Carbolite Housing: The heat-resistant housing made of arc-resistant plastic ensures safe extinguishing of the electric arc and resistance to heating.
- High Reliability of the Contact Group: Designed for intensive operation in industrial environments and infrequent operational switching (up to 30 on/off cycles per day).
- Wide Application: Suitable for the protection of three-phase power cable lines, electrical installations, machine tools, and low-to-medium power asynchronous electric motors.
Compatibility and Scope of Application:
- Industrial distribution boards (ShO-70, VRU, MSB).
- Protection and operational switching of asynchronous three-phase electric motors with power up to 11 kW (at 380 V).
- Power circuits of technological equipment, machine tools, pumping and ventilation units.

Pro Tip: Before installation and connecting the power cables, ensure that there is no voltage on the line. When clamping cable lugs on the power terminals of the circuit breaker, tighten the screws with sufficient force, and after 1–2 months of operation, re-tighten the contact connections to prevent terminal overheating due to loosening.
