ABJ2-70W Single-phase Two-wire AC Voltage & Current Protector (For Tripping Circuit Breakers)
- Shanghai Chaoshi Electronic & Electrical Equipment Co., Ltd.
- product brand:Shanghai Chaoshi Electronic & Electrical Equipment Co., Ltd.
- Numéro de stand：E2G36
- product specification:61 (L)x20.5 (W)x73 (H)mm
- product category:Refrigeration Equipment-Components for refrigerating systems and plants-Miscellaneous components for refrigerating systems and plants
- product introduction:Features:
· Both voltage and current protection in one product
· Used in conjunction with circuit breakers with tripping functions
· Simple and reliable protective circuit
· Convenient line detection
· High precision; low temperature drift
· Applicable to the protection of home-use charging devices and home-use power distribution equipment
Functions:
· Protection functions: Overcurrent protection, over-/undervoltage protection, instant supervoltage protection (25%)
· Actuation time: When over-undervoltage protection and electrification of zero line protection take actions, the actuation time of the protector is less than 3 seconds, in order to prevent malfunctions caused by voltage or current fluctuation; When the overcurrent is smaller than 25%, the actuation time of the protector is less than 5 seconds. (Duration of the actuation time can be chosen based on the load magnitude.)
· Delay recovery: After the protector acted, it will delay for 3min before getting back to work, and it will reset the power. (Depending on different control circuits, there is probably no delay recovery process.)
· Protection against backlash voltage during undervoltage protection: 2+1VAC
· Contact forms: 1 set of change-over contacts + 1 set of NO contacts
· Accuracy of voltage setting: <0.5% (Set value x 0.5%);
Temperature drift: <0.05V/℃ (Benchmark temperature: 25℃)
Dimensions:
61(L)x20.5(W)x73 (H)mm
