Siemens Sentron 5SY4 MCB, 1P, 4A Curve C, 230V AC, 10 kA Breaking Capacity

Want a miniature circuit breaker with the versatility to protect both AC and DC applications? Choose this small but mighty MCB from Siemens. It automatically shuts down an attached electrical circuit in case of overcurrent conditions to keep you safe and prevent damage to a connected device. As a type C module, it trips when it receives more than five to ten times its rated load of 4A, so it's ideal for industrial settings where high-power loads are common. You'll find it's compatible with AWG gauges 18 to 4, since it accepts any wire with a cross-section between 0.75 and 35mm².

• Works in AC or DC applications thanks to separate AC and DCbreaking capacities of 10kA and 15kA respectively
• Straightforward single-pole device lets you protect one circuit
• Free of halogen and silicone, so you can trust it won't produce toxic fumes in case of fire
• Resistant to shock and vibration, so it's suitable for use near moving machinery

Yes – its IP20 rating means you can trust it's touch-proof and poses no shock risk.
