DESCRIPTION

The 21.305.0453.0 is a 4-pole electrical connector terminal block with integrated wire protection (DSI - Dielectric Strength Insulation) designed for secure electrical connections in industrial control and power distribution applications. It features a 300 V rated voltage with a 20 A contact current rating per pole, meeting VDE 0110, UL, and CSA approvals. The connector accommodates wire gauges from No. 22 to No. 12 AWG and is configured with 4 poles, providing a compact footprint with 30 mm overall width (G) and 24 mm terminal depth (T). The wire protection design prevents accidental contact with live terminals, making it suitable for panel-mounted installations, machinery control cabinets, and industrial automation systems where safety and reliability are critical.
