Product details
WAGO Corporation's 280-521 delivers industrial-grade Terminal Blocks - Din Rail, Channel performance for mining equipment. The dust-proof construction and impact-resistant design ensure reliable operation in open-pit and underground mining applications.Featuring Disconnect, Feed Through reinforced isolation, this terminal block withstands mechanical shock up to 100G. The ceramic-filled housing material exceeds MSHA requirements for mining equipment.The Disconnect Tab mechanism enables safe isolation during equipment maintenance. The bright yellow actuator provides clear visual indication of circuit status.The 4 position configuration supports complex dragline and shovel electrical systems. Each contact features silver-nickel alloy for optimal performance in sulfur-rich environments.With 2 independent levels, the design separates high-voltage power from control circuits. The vertical barriers provide 12kV impulse withstand capability for lightning protection.The 5.0mm terminal size accommodates mining-grade feeder cables. The anti-vibration design maintains contact pressure during continuous equipment operation.Utilizing Push In, Spring technology, the connection system resists dust ingress per IP68 standards. The tool-less design enables maintenance in confined spaces.Rated for 10 A continuous current, the terminal meets IEC 62031 requirements for mining applications. The thermal design handles 300% overload during motor starts.With 400V working voltage, the component exceeds high-voltage shovel requirements. The tracking resistance exceeds CTI 800 for reliable operation in coal dust environments.Compatible with 12-28 AWG mining cables, the terminals feature integrated abrasion-resistant boots. The dual-compression design prevents strand breakage in flexible conductors.The Gray housing meets mining visibility requirements for low-light conditions. The photoluminescent markers remain visible for 12+ hours after charging.
