FAQs
The ABB 1SDA064879R1 uses fixed front terminals designed for quick, secure wiring in Tmax T assemblies. Before installation, verify panel clearance, mount the device on the DIN rail or chassis as specified, and route conductors to the front terminals to minimize wiring length. Ensure the release PR332/P LSIG is correctly positioned to achieve selective tripping and confirm torque values per installation manual.
This device has UL489-compliant interrupting ratings of 65 kA at 240 V, 50 kA at 480 V, and 25 kA at 600 V. It is rated for 1200 A continuous current (I_n) with a rated operational voltage of 630 V AC and an insulation voltage of 1000 V. Its test voltage max is 3500 V, and it uses the PR332/P LSIG release for reliable performance.
Yes. The 4P Tmax T design, high current rating, and UL/CSA approval make it suitable for transformer and generator protection. Its 8 kV impulse withstand and 1200 A runtime support reliable switching in low-voltage distributions, while front-terminal wiring aids integration in space-constrained protection panels commonly found in power generation and transformer housings.
The unit carries CE conformity and UL/CSA listings, alongside RoHS and REACH declarations. It also references CMRT and TSCA documentation for conflict minerals and chemical safety reporting. These certifications simplify cross-border procurement and regulatory compliance in multinational projects and supplier risk management.
With a mechanical durability rating of 10,000 cycles at 60 cycles per hour and a per-pole power loss of 47 W, the MCCB delivers predictable lifecycle performance and energy efficiency. Front-terminal installation reduces wiring wear during maintenance, and the robust Tmax T build minimizes downtime in continuous-operation environments such as manufacturing lines and critical facilities.
