The 280-502/281-589 is a double-deck component terminal block designed for surge suppression and secure wire termination. It incorporates a 1.5KE33C TVS diode to protect 24 VDC systems against overvoltage and utilizes WAGO's CAGE CLAMP® technology for reliable connections with conductors up to 2.5 mm². This gray terminal block includes an end plate and allows for direct connection to both 35 x 15 mm and 35 x 7.5 mm DIN-rails. Its slim, space-saving design is ideal for applications requiring high operational reliability and protection against unplanned downtime in control systems.
