B-LINE SPHM2RM0010 – Frequently Asked Questions
1) Can I use the B-Line SPHM2RM0010 supplementary protector as the main branch circuit breaker in a panelboard?
No. The SPHM2RM0010 is a supplementary protector, not a branch circuit breaker. Supplementary protectors provide additional overcurrent protection downstream of a circuit already protected by a branch breaker, typically inside equipment or a control panel. It does not replace the branch circuit protection required at the panelboard.
2) Will the B-Line SPHM2RM0010 nuisance trip on motor or transformer inrush?
It is built to ride through startup surge. The hydraulic magnetic design carries a medium time delay with an inrush withstand of 18 times rated current, so a motor, transformer or switching power supply drawing a short high-current spike at energization will not trip it at 10A. Sustained overload is what opens it.
3) Can I mount this B-Line supplementary protector in a wet or dusty location?
No. The protector is IP20 rated, which means it is finger-safe against solid objects 12.5 mm and larger but has no protection against water or fine dust. Mount it inside an enclosed control panel or cabinet that provides the environmental rating the location requires.
4) Is this B-Line protector single pole or two pole, and can it protect both legs of a 240V circuit?
It is a two-pole device, so it breaks both current-carrying conductors at once. That suits ungrounded two-wire circuits and 240V single-phase loads where code or the equipment spec calls for both legs to open together.
5) Does the SPHM2RM0010 work on both 50 Hz and 60 Hz power?
Yes, it is rated 50-60 Hz, so it can go into equipment built for North American 60 Hz service or exported to 50 Hz markets without changing the protector.
6) Why choose a hydraulic magnetic protector over a thermal one for a control panel?
Hydraulic magnetic tripping is not affected by ambient temperature, so the 10A trip point stays the same whether the panel is running hot inside an enclosure or sitting in a cold plant. A thermal-magnetic device shifts its trip point with surrounding heat and often has to be derated. For panels that see wide temperature swings, the hydraulic magnetic approach keeps protection predictable.
7) What model do I order to get this exact B-Line protector, and where can I confirm the trip curve?
Order by Eaton B-Line part number SPHM2RM0010. The manufacturer spec sheet is linked from the product description and carries the detailed trip curve data for the medium delay characteristic.
