Product details

Dimensions: 97 mm deep, 60 mm wide, 85 mm high. Terminals accept solid conductors: 2x (0.5–1.5 mm²) and 2x (0.75–2.5 mm²); stranded conductors up to 10 mm². That covers most control-circuit wire gauges without need for ferrules, though stranded runs benefit from them under repeated flex.
