Item Info
|
★1SDA073700R1 is a genuine Undervoltage Release (YU) electromagnetic coil manufactured by ABB as an internal electrical accessory for high-capacity power circuit breakers. It is explicitly designed for integration within the ABB SACE Emax 2 (Frames E1.2 to E6.2) Air Circuit Breakers (ACB) and the SACE Tmax XT (XT7/XT7M) Molded Case Circuit Breakers (MCCB).The primary function of this undervoltage release coil is to serve as a fail-safe safety mechanism. It continuously monitors the control voltage supply of the power distribution network. If the network voltage drops significantly or experiences a total power failure (falling below a safe operational threshold), the coil instantly de-energizes, mechanically tripping the circuit breaker to isolate downstream equipment from potential damage. Engineered with a universal electrical layout, it handles supply networks operating anywhere between 220V and 240V across both Alternating Current (AC) and Direct Current (DC) configurations. |

FAQ
Q: What is ABB known for in the industrial automation industry?
A: ABB is a global leader in power and automation technologies . The company is renowned for its comprehensive portfolio of industrial drives (ACS series), robotics, distributed control systems (800xA), and PLC systems (AC500). ABB products are widely used across power generation, oil and gas, chemical manufacturing, mining, and heavy industry applications .
Q: Are ABB products compatible with each other across different series?
A: Generally, yes. ABB designs its products with backward and cross-series compatibility in mind. For example, the KVC758A board is specifically designed for ACS5000 drives but is also compatible with ACS800 and ACS880 cabinets . Similarly, ABB's Advant OCS 800xA DCS systems integrate with various ABB drive platforms, allowing for seamless system expansion and upgrades .
Q: What makes ABB products suitable for harsh industrial environments?
A: ABB products are engineered with industrial-grade specifications including :
·Wide operating temperature ranges (e.g., -40°C to +70°C for the KVC758A)
·High electrical isolation ratings (520 VDC or higher) to protect against voltage transients and ground loops
·Electromagnetic resilience to withstand noisy industrial environments
·Robust construction with protection against dust, moisture, and vibration
·Built-in protection mechanisms including overvoltage and overcurrent safeguards
