ABB 1SVR740100R0300

The CT-ERS.21P operates as a single-function electronic time relay within the CT-S timer range, specifically providing an ON-delay (delay on make) capability. This device supports a control supply voltage ranging from 24 to 240 V AC/DC and is equipped with a dual changeover (SPDT) output rated for 250 V and 4 A. The relay's compact dimensions include a width of 22.5 mm, a height of 85.6 mm, and a depth of 103.7 mm, with a weight of 0.121 kg.

Users benefit from Easy Connect Technology that utilizes screwless push-in terminals, facilitating straightforward installation and maintenance. The device also features a transparent cover to prevent unauthorized adjustments. Its operational temperature range spans from -40°C to +60°C, ensuring performance in various environmental conditions.

Compliance with standards such as CAN/CSA C22.2 No.14 and IEC/EN 61812-1 ensures reliability and safety. The CT-ERS.21P's rated impulse withstand voltage stands at 4 kV for both input and output circuits, while its degree of protection is IP50 for the housing and IP20 for the terminals. This time relay is suitable for applications requiring precise timing controls in industrial settings.
