Air Circuit Breaker
ACB: SENTRON 3WL
Reliable, versatile and perfectly integrated.
All power distribution systems rely on a secure infeed of electrical energy. The 3WL air circuit breakers reliably protect electrical equipment from damage or fire resulting from short circuit, ground fault or overload failures.
Flexibility
• New electronic trip units (ETU) with outstanding features.
• Only two frame sizes cover a broad range of applications from
400 A to 4000 A, up to 66 kA at 500 V, 3- or 4-pole
version, fixed-mounted, withdrawable version.
• All components can be combined in a modular way
Ease of use
• User friendliness in planning, configuration, installation and
operation.
• Wide range of accessories for both frame sizes can be
easily retrofitted.
• Displays for all electronic trip units (ETU).
Safety and reliability
• International and standardized processes ensure highest
product quality.
• Conforms to international standards and approvals

ATC 5300
The SENTRON ATC5300, when equipped with two motor-driven circuit breakers,
serves as a transfer system that automatically or manually switches between two
power supply systems in low-voltage power distribution applications.
Mouded Case Circuit Breakers
The new 3VA circuit breakers set new standards in terms of flexibility and variety of modular accessories. Standardized accessories suitable for use with several sizes of circuit breaker from all the 3VA ranges help to cut costs and save installation time.

Switching Devices
CONTRACTOR RELAYS-3RH2(S00)
Contactor relays are switching devices for control and auxiliary circuits and are used for controlling, signaling and locking switching devices and switchgear. Naturally, SIRIUS 3RH2 contactor relays come with standard-compliant connection designations and a connection system that saves both time and installation overhead. This makes them particularly suitable for practical applications. 3RH2 contactor relays and size S00 motor contactors are the same size and have an identical design – a significant advantage, particularly with regard to the accessories.
They are designed for AC or DC operation and are available with screw or spring-loaded terminals. The basic version of the contactor relays is a 4‑pole design which can be extended up to eight poles by means of snap-on auxiliary switches
The SIRIUS modular system with its components for the switching, starting, protection and monitoring of motors and industrial systems stands for the fast, flexible and space-saving construction of control cabinets.
