Product details

The Siemens 5SY4563-7CV is a 1-pole-plus-neutral miniature circuit breaker (MCB) with a C63 tripping curve and a 15 kA interrupting capacity (Icu) at 230/400 V AC.

The 1P+N form factor occupies a single DIN-rail module width and switches the line conductor only, with the neutral bar through the breaker for isolation. The C63 rating (63 A nominal, C-curve) means magnetic trip occurs at 5–10× In (315–630 A), so it tolerates the starting surge of a 15 kW motor or a bank of LED drivers without tripping, but still clears a hard short fast enough to protect downstream cable.

Frequently asked questions

Where can I buy the 5SY4563-7CV and get a price?

The 5SY4563-7CV is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead-time estimate.

What is the interrupting capacity of the 5SY4563-7CV?

The 5SY4563-7CV has a 15 kA interrupting capacity (Icu) at 230/400 V AC, which means it can safely clear a fault up to 15,000 amps on a 400 V three-phase supply.

What does the C63 rating mean on this MCB?

C63 means a 63 A nominal current rating with a C-curve trip characteristic — magnetic trip between 5× and 10× rated current (315–630 A), suited for motor and transformer loads with moderate inrush.
