What is Switchgear and Control Gear?

Switchgear is a collective term for electrical disconnect switches, circuit breakers and fuses that ensure that electrical equipment is controlled, isolated and protected. Generally speaking, low, medium and high voltage switchgear is employed in power distribution applications. Control gear that is low or medium voltage is generally used in industrial applications where electrical equipment – particularly electric motors - needs to be protected from earth faults, surges and short circuits. It also provides simple control functions such as stop/start and building up motor speed.

E-T-A Miniature Circuit Breakers MCBs

UL 489 and UL 1077 – Designed for AC and DC

MCBs are essential components in electrical systems. They are designed to protect applications and electrical loads against the dangerous consequences of overcurrents.

While MCBs according to UL 1077 provide additional protection for low voltage applications, the MCBs according to UL 489 are designed to provide reliable protection for a wide range of applications and voltage ranges.

Our thermal-magnetic MCB portfolio (4230-T) includes both UL 1077 and UL 489 versions have rated currents from 1 to 63 A with different characteristics and numbers of poles. The 4230-T…U product group (UL 489) is suitable for circuit protection in AC or DC networks, the 4230-T…E product group (UL 1077 / EN 60947-2) is designed for additional protection.

The UL 508A standard specifies the requirements for the construction and installation of control panels to ensure that they comply with electrical safety standards. Among other things, the standard covers the design, wiring and operation of control panels and guarantees that they can control electrical systems safely and reliably.

Our 4230-T MCB is suitable for use in switchgear according to UL 508A. Each load can be individually protected according to the standard.

Typical Applications:

Automotive manufacturing
Chemical, oil and gas industry
Automation and building technology
Telecommunications and data centres
