ABB S282UC-K2 GHS2820164R0277 S280UC Miniature Circuit Breakers MCBs

Description

The S282UC-K2 universal current miniature circuit breaker with Product ID GHS2820164R0277 is a 2-pole electrical device engineered to deliver comprehensive current limitation, short-circuit protection, and overcurrent mitigation. As part of the S280UC product series, this unit features a delayed thermal tripping mechanism for overload protection and an electromechanic magnetic tripping mechanism for short circuit protection. It is specifically optimized with a high DC voltage rating to serve as a reliable solution for direct current sub-circuits up to 440 V DC across two poles, making it highly compatible with applications in photovoltaics, telecommunication infrastructure, electric traction setups, and specialized industrial settings.

Features

• Equipped with a 2-pole hardware architecture supporting multi-line configuration protection.
• Utilizes a K-characteristic tripping curve designed to handle specific inductive current parameters.
• Features a universal current architecture certified for both alternating current and high-voltage direct current distribution.
• Incorporates an insulation group I housing finished in RAL 7035 with a sealable black insulation group II actuator handle.

Applications

• Photovoltaic power string arrays and solar combiner panel boxes.
• Telecommunication power backup networks and traction sub-stations.
• Industrial direct current control circuits requiring specialized branch circuit overcurrent protection.

Installation Guidelines

• DIN Rail Installation: Secure the unit onto standard symmetrical tracks including TH35-7.5 (35 x 7.5 mm mounting rail) or TH35-15 (35 x 15 mm mounting rail) in compliance with IEC 60715.
• Mounting Position: The mechanical frame allows assembly at any functional orientation angle.
• Polarity Tracking: Ensure specific attention is paid to the verified polarity markings of the device during direct current circuit wire placement.
• Terminal Connections: Connect conductors tightly to the integrated cable clamp screw terminals using a Pozidriv 2 tool to ensure a torque of 2.5 N-m.
