The Schneider Electric Circuit Breaker GB2CD21 is a TeSys GB circuit breaker, 2-pole (1P+N), 16A/250V IEC/277V UL, designed to protect control circuits in industrial installations. It offers thermal-magnetic protection with a magnetic tripping value of 220A (13 In) and a breaking capacity of Icu 1.5kA@240V. It can also be used to protect DC loads up to 16A/24V DC-13 with a breaking capacity Icu 1.5kA@24V. The compact device is 30 mm wide, mounts on a 35 mm DIN rail, and can be controlled via a toggle switch (start-stop guaranteed for 8000 cycles). It is sold in packs of 3 units and is certified according to several standards (IEC, UL, CSA). Additionally, it is a Green Premium product (RoHS/REACh).
