DC rated performance with 500 V DC operation and 16 A nominal current provides robust protection for DC distribution panels, reducing nuisance trips and enabling safe fault clearance in critical systems. Front-terminal design and fixed mounting streamline installation in compact enclosures, lowering wiring complexity and service time for panel builders. The thermomagnetic release (TMD TM) delivers fast, selective tripping, improving system uptime and limiting collateral damage during faults. A power loss of 1.33 W per pole supports cooler cabinet temperatures and energy efficiency across the board, while a 25,000-cycle mechanical durability rating ensures long service life in high-cycle applications. EcoSolutions features, including End Of Life disassembly guidance and recyclability considerations, support sustainability goals and regulatory compliance.

FAQs
The ABB 1SDA123508R1 uses a fixed front-terminal configuration for straightforward panel mounting. Ensure the panel provides 500 V DC rating and space for a four-pole device. Verify clearance for front-terminal connection, tighten terminals to the recommended torque, and confirm proper seat and isolation before energizing. The device is designed for quick integration with minimal wiring complexity, reducing commissioning time.
Key specs include a rated current of 16 A, rated insulation voltage of 1000 V, and rated operational voltage of 500 V DC. Short-circuit performance is 36 kA in series for both 250 V DC and 500 V DC configurations, with an impulse withstand voltage of 8 kV. Power loss is 1.33 W per pole, and the unit uses a TM/TMD release for selective tripping.
Yes. Its DC ratings, high short-circuit withstand capability, and front-terminal installation suit data centers, renewable energy storage, and other DC distribution needs. The four-pole, fixed-design supports space-efficient cabinet layouts, while IEC 60947-2 compliance and RoHS/REACH align with industry standards and sustainability goals.
The product conforms to IEC 60947-2 and GB/T 14028.2, with CE labeling. It is documented under ABB EcoSolutions for sustainability programs, including end-of-life disassembly instructions and environmental declarations (EPD). RoHS and REACH declarations are provided, supporting regulatory compliance in multiple markets.
Expect low maintenance due to high mechanical durability (25,000 cycles) and a compact, low-loss design (1.33 W per pole). Its front-terminal access reduces maintenance time and error rates during servicing. Over time, the high reliability and compliance with key standards help reduce downtime, improve panel uptime, and lower total cost of ownership.
