New compact terminal block delivers fast and reliable toolless installation

The steady progress in digitalisation and the ever-increasing complexity of electrical wiring layouts demand innovative developments in distributor technology. In this context, WAGO’s latest 221-420 terminal block represents one big step forward in saving time and space, compactness, and versatility, setting new standards for electrical connectors. The Conrad Sourcing Platform now supplies this innovative product.

Unlike jumpers, this latest terminal does not decrease the number of contacts. The 420 terminal of the 221 series features ten contacts for wires of a similar electrical potential that enable easy toolless installation. The product supports single-core wires with cross-sections from 0.14mm² to 4mm² and multi-core cables sized 0.2mm² to 4mm². Moreover, the compact two-tier design makes the terminal the go-to choice for limited board space.

The terminal has a 450V rating and a current rating of 32A. This increases its range of uses if users want to wire distributors and switchboards that control blinds, heating systems, supply technology, intercoms, electrical cookers, and many other appliances in buildings.

The terminal block uses CAGE CLAMP technology – a reliable maintenance-free wiring method centred around spring-loaded contacts. This makes time-consuming pre-installation procedures such as crimping lugs on wire ends redundant, speeding up the work of electrical contractors and equipment manufacturers' production lines. WAGO also pay great attention to user safety. The product’s transparent casing allows easy visual inspection of each wire that complies with applicable standards. Moreover, the terminal sports openings at the front and the back, enabling users to check the wire contact after the terminal has been installed.

WAGO supplies various fixings for its terminal, including strain reliefs and adapters with and without latches that allow the product to be mounted rail in upright and horizontal orientations. Moreover, it also offers a certified explosion-proof version complying with ATEX standards and a sustainable Green Range edition.
