RS PRO Mains Test Block Cable Entry 4 to 7 mm, 240V AC, 13A, Quicktest QT1, Impact-Resistant Plastic 458-926

The RS PRO 458-926 Mains Test Block is a precision device designed to facilitate safe and reliable temporary mains power connections for laboratory, test bed, and service area applications. Engineered for cable entry ranges from 4 to 7 mm, this test block provides flexible connectivity options, accommodating various cable types used in professional environments. It features the Quicktest QT1 connector, which allows fast insertion and secure clamping of plugless leads in its colour-coded insulated clips.

This versatile block is rated for 240V AC and supports currents up to 13A, making it suitable for electrical testing of equipment and appliances in controlled, non-domestic settings. The device is built with tough, impact-resistant, flame-retardant plastic to ensure safety, durability, and compliance with demanding laboratory and industrial standards. The neon indicator on the block offers clear visual confirmation of live circuit status, aiding operators in safe power management during testing procedures.

When the lid is open, wires from the test lead can be inserted into insulated clips, which are colour coded for identification and provide complete electrical isolation. Closing the lid enables current flow to the device under test. This design minimises risk and enables secure power delivery during measurement, calibration, and troubleshooting operations.

The RS PRO 458-926 model does not include a fixed cord, providing greater flexibility for lead selection and direct wire insertion. Its compact dimensions - 48 mm in height, 60 mm in width, and 127 mm in depth - allow easy placement on laboratory benchtops, test stands, and maintenance stations. The block integrates a 13A fuse and neon indicator for operator safety, with durable construction to withstand repetitive use.

Typical applications include electrical laboratories, test benches for equipment verification, field service areas, and other professional environments where safe, temporary mains connections are required. The block's design enables fast setup and teardown during routine inspections or experimental procedures, supporting a wide range of voltages, currents, and cable configurations.

The RS PRO 458-926 Mains Test Block is an essential accessory for electrical engineers, technicians, and laboratory personnel, enabling precise and safe power connection management. Its advanced safety features and robust construction help ensure reliable operation in technical and industrial contexts.
