Product details

160 A frame, 163 A instantaneous trip — what that means on the line

The ABB 1SDA053142R1 is a T2H160 series molded case circuit breaker, 3-pole, built around a 160 A frame with a 163 A instantaneous magnetic trip element. That trip rating is the fixed magnetic pickup — it's not adjustable, so when you spec this into a panel the short-circuit protection threshold is locked at 163 A per pole. The 160 A frame gives you the thermal capacity for continuous current up to that level, but the magnetic trip clears faults above 163 A without waiting for thermal bi-metal lag.

Where this MCCB fits in a panel

This is a fixed thermal-magnetic MCCB — no interchangeable trip units, no electronic adjustments. It's the kind of breaker you drop into a distribution board where the load is known and stable: motor branch circuits, feeder protection in a lighting panel, or a downstream sub-feed where coordination with an upstream main breaker is already calculated.

Frequently asked questions

What does the 163 A instantaneous magnetic trip mean for coordination?

The 163 A magnetic trip is the fixed short-circuit pickup for each pole. It's not adjustable, so the breaker clears faults above 163 A instantaneously. For selective coordination with an upstream breaker, you need the upstream device's instantaneous pickup to be at least 1.3 to 1.5 times 163 A (around 212 to 245 A) to avoid nuisance tripping on downstream faults. The 160 A frame thermal rating handles continuous currents up to 160 A per pole without tripping.

What compliance documentation does ABB provide for 1SDA053142R1?

ABB provides standard compliance documentation for the T2H160 series, including IEC 60947-2 certification for molded case circuit breakers. The documentation typically covers RoHS and REACH compliance. For specific UL or CSA documentation, check the ABB product drawing or contact the supplier with your regulatory jurisdiction requirements.
