Allen-Bradley 1489-M1C060 Thermal-Magnetic Circuit Breaker

1. Product Description

The 1489-M1C060 is a single-pole (1P), 6A, C-type trip characteristic miniature circuit breaker (MCB) from Allen-Bradley’s 1489-M series. It is designed for branch circuit protection in industrial and commercial applications, complying with UL 489 (USA/Canada) and IEC 60947-2 (international) standards. This thermal-magnetic breaker is ideal for protecting circuits with moderate inrush currents, such as lighting, control circuits, and small motors .

2. Key Features

C-Type Trip Curve – Trips at 5–10 times the rated current (6A), suitable for circuits with moderate inrush currents (e.g., transformers, solenoids) .
Dual-Terminal Design – Allows connection of two wires or one wire and a busbar, improving wiring flexibility .
High Durability – Resistant to shock, vibration, and extreme temperatures (-25°C to +55°C) .
Reversible Line/Load Connections – Simplifies installation in various configurations .
Hot-Swappable Accessories – Supports auxiliary contacts, shunt trips, and lockout/tagout (LOTO) devices for enhanced safety .
