What is a Circuit Protection device?

A circuit protection device is a fail-safe device that originates a disruption in an electrical circuit when it recognizes an excess and unsafe power load in a circuit. The main aims of circuit protection are to localise and isolate the situation or fault and avert and minimize any unnecessary power loss.

What Do We Supply?

We have broad selection of circuit protection devices, including:

Circuit breakers

Thermal circuit breakers

Thermal-magnetic circuit breakers

Magnetic circuit breakers

Hydraulic-magnetic circuit breakers

Fuses

LV fuse links

LV fusegear

E-T-A Timer Relays

Timer relays are especially suitable for the use in passenger cars, trucks, buses as well as construction machinery and emergency vehicles. They control pumps, valves or motors, which are meant to overtravel or stay open for a defined period of time. They equally control the co-ordinated, sequential switch-on of loads to avoid load peaks (e.g. with fans).

E-T-A timer relays are available for DC 12 V and DC 24 V applications and are suitable for standard automotive relay sockets to ISO 7588.

Key Features:

Functions: Provide ON delay, OFF delay, and interval timing, allowing for flexible, programmable operation.
Technical Design: Features include solid-state reliability
Installation: Designed to fit standard automotive relay sockets to ISO 7588, facilitating easy replacement.

Key Benefits:

Load Management: Enables sequential switching to avoid power peaks and protects batteries.
Durability: Engineered for harsh conditions with robust construction.
Customization: Offers flexible, programmable parameters for specific vehicle needs.

Applications:

Buses
Trucks
Construction Machinery
Specialized Vehicles
Protecting Circuits and Controlling Devices that need to run for a specific duration

Schurter 4792: Outlet 16A for Flexible Wiring

4792 – Outlet 16A for Flexible Wiring

Mechanically Robust Design
Available in Three Colors: Black, White, Grey
90° Rotated Terminals

When space is limited and wiring must be efficient, every detail counts. The new Schurter 4792 outlet type J offers an intelligent solution: horizontally aligned connections, rotated 90° compared to standard designs. This variant facilitates wiring in power distribution units (PDUs).

The 4792 outlet combines space-saving design with easy installation. The snap-in mounting system for wall thicknesses from 0.8 to 3.0 mm (standard: 1.2 and 1.5 mm; variants on request) enables quick and secure installation.

Available in black, white, or gray, the 4792 outlet offers greater design freedom for a variety of applications. With several connection options (standard: QC 6.3 mm; QC 4.8 mm, solder or PCB connections available on request), it offers various wiring possibilities. Certified according to VDE, UL, and CCC, the 16 A outlet guarantees worldwide conformity and safety.

The new 4792 outlet with a rated current of 16 A is suitable for use as a component in power distribution units (PDUs), which are used in particular in data centers, but also for other applications such as industry, IoT, and IT/telecommunications.
