FAQs
This 4P moulded case circuit breaker uses front-terminal connections, simplifying wiring in control panels and distribution boards. Plan for secure terminal torque, appropriate clearance for front-access maintenance, and compatible mounting within standard 125 A, 690 V bus configurations. The unit’s compact width of 101.6 mm and height of 130 mm support dense panel layouts, while the 60 mm depth helps fit shallow enclosures without compromising accessibility.
TMF release provides coordinated tripping with a thermal-magnetic mechanism, delivering fast opening times (as low as 15 ms per operating mode) and reliable fault interruption. With 4P configuration and up to 50 kA Ics at 240 V, the device supports strong short-circuit protection while maintaining selectivity with upstream devices, reducing the likelihood of cascading outages in complex feeders.
Yes. The 1SDA066768R1 is designed for transformer protection and LV distribution, with a rated insulation voltage of 690 V and a rated operational voltage of 550 V AC / 250 V DC. Its 125 A main current rating and front-terminal termination make it ideal for transformer-fed feeders, enabling reliable protection and straightforward integration into control cabinets and marshalling panels.
The device carries CE conformity (EC Declaration of Conformity Formula DSA A1), RoHS compliance, and REACH declarations, along with TSCA reporting. These certifications support regulatory compliance across Europe and other regions, facilitating procurement and reducing supplier qualification risk for multinational projects in process industries and utilities.
The MCCB combines a durable mechanical life (8500 cycles) with electrical durability (1500 cycles) and low power loss (11 W per pole), which translates to lower energy waste and fewer maintenance events. The front-terminal design, compact footprint, and high short-circuit robustness help reduce installation time and panel space, delivering lower lifecycle costs and a faster payback in high-volume production environments.
