Eaton CHSPT2MICRO – Frequently Asked Questions

1) What is the difference between the Eaton CHSPT2MICRO, CHSPT2MAX, and CHSPT2ULTRA surge protective devices?
They are the same CHSP Type 2 service entrance family, single-phase, separated by nominal discharge current (In). The CHSPT2MICRO is rated 5 kA, the CHSPT2MAX 10 kA, and the CHSPT2ULTRA 20 kA. Nominal discharge current is how many repeat surge hits at that current level the device is tested to survive, so the higher rating is the one to pick where lightning activity is heavy or the service feeds equipment you cannot afford to lose. All three share the same 150V L-N / 300V L-L operating voltage and the same protection levels.
2) Will the Eaton CHSP Type 2 surge protector work on a 120/240V single phase residential panel?
Yes. The CHSP is a single-phase device with a 150V L-N, 300V L-L operating voltage rating at 60 Hz, which covers a standard 120/240V single-phase service. It is not suitable for three-phase service equipment or for 277/480V systems.
3) Can the Eaton CHSP surge protective device be mounted outdoors next to the meter?
The CHSP comes in a NEMA 4 enclosure, which is rated for outdoor use against rain, windblown dust, and hose-directed water, so it can be surface mounted outside alongside service equipment. It is also rated for -40 to 50 degrees C ambient, so cold-climate exterior walls are within its range.
4) Does a Type 2 SPD like the Eaton CHSP go on the line side or the load side of the main breaker?
Type 2 is a load-side device. The CHSP is installed on the load side of the service disconnect, typically fed from a two-pole breaker in the panel or landed on the panel bus. If you need protection ahead of the main disconnect, on the line side of the service, that is a Type 1 device and this is not it. Type 2 is the usual choice for a panel-mounted service entrance SPD in a house, a multi-unit building, or a light commercial suite.
5) What are the let-through voltage protection ratings on the Eaton CHSP surge protector?
Voltage protection is 600V line to neutral, 1000V line to line, 800V neutral to ground, and 600V line to ground. Those are the clamping levels the connected equipment sees during a surge, and they are the numbers to put against an equipment spec when an owner asks whether sensitive loads (elevator controls, HVAC boards, POS gear) are covered.
6) Is the Eaton CHSP surge protector UL listed?
The CHSP is built to UL 1449 3rd Edition and the device carries cUL marking as well, so it satisfies both US and Canadian listing requirements for a Type 2 SPD. It also meets the requirements specified in IBC 2006, CBC 2007, and UBC Zone 4.
7) Can the Eaton CHSP be installed on a panel with a high available fault current?
Yes. The CHSP carries a 200 kAIC interrupt rating, so it can be applied on service equipment where the available fault current is high, including commercial services close to a large utility transformer. Confirm the panel's own series rating covers the installation as well.
8) How many surge protectors do I need for a building with multiple panels?
One CHSP at the service entrance handles the surges coming in from the utility, but it does not protect a downstream subpanel from surges generated inside the building, and the further a load sits from the SPD the less benefit it gets from it. For a multi-unit property or an office with remote subpanels, the usual approach is one device at the service and an additional Type 2 device at each subpanel feeding sensitive equipment. Since the CHSP is single-phase at 150V L-N / 300V L-L, use it only at panels on a single-phase supply.
9) Will the Eaton CHSP surge protector hold up in an unheated garage or a northern climate?
Operating range is -40 to 50 degrees C (roughly -40 to 122 F), which covers unconditioned garages, mechanical rooms, and exterior walls in cold climates. Paired with the NEMA 4 enclosure it is meant for weather-exposed service equipment rather than indoor-only mounting.
10) Is the Eaton CHSP surge protector a one man install, or does it need a lift or extra hands?
It weighs 1 lb, so it is a one-hand mount on the wall or panel side and no lifting help is needed. The labor on the job is the conduit nipple, the two-pole feed, and keeping the SPD leads short and straight, not the weight of the device.
