Intermatic IG1240RC3 – Frequently Asked Questions

1) Can the Intermatic IG1240RC3 surge protective device be mounted outside next to the meter, or does it have to go indoors?
Either works. The IG1240RC3 comes in a Type 3R rainproof plastic enclosure, so it can hang outdoors at the service entrance or indoors next to a panel. The housing is gray plastic and measures 4.188 in high by 4.188 in wide with a 3.438 in depth, so plan for roughly that much wall space plus conduit bend radius at the knockout.
2) Will this Intermatic surge device work on a standard 120/240V single phase residential panel?
Yes. The IG1240RC3 is rated 120/240 VAC single phase, which is the standard split-phase service in US homes and light commercial buildings. It is not a three phase or 208Y/120 device, so for a wye or delta commercial service you need a different SPD.
3) What does Type 1 or Type 2 mean on the IG1240RC3, and where in the system can I install it?
It is classified as both Type 1 and Type 2, which means it can be installed on the line side of the main service disconnect (Type 1, no external overcurrent protection required) or on the load side of the main breaker in a downstream panel (Type 2). That flexibility lets you put it at the meter, at the service entrance, or at a subpanel feeding sensitive loads.
4) Is the Intermatic IG1240RC3 UL Listed for code compliance on a permit job?
It is UL Listed to ANSI/UL 1449 5th edition, the current SPD standard inspectors look for. That listing plus the Type 1/Type 2 classification is what lets it be accepted either ahead of or behind the service disconnect.
5) What are the six modes of protection on this Intermatic SPD?
Six-mode protection means the device clamps surges across every conductor combination on a 120/240V single phase service: each hot to neutral, each hot to ground, hot to hot, and neutral to ground. Three-mode units skip some of those paths, which leaves equipment exposed to surges that arrive between neutral and ground, a common path on older or long service runs.
6) How do I tell if this surge protector has taken a hit and needs replacing?
There is a green LED on the front. Lit green means the protection modes are intact; if it goes dark, the device has sacrificed itself and should be swapped out. Worth telling maintenance staff to eyeball it during routine panel checks, since an SPD gives no other outward sign it has failed.
7) Is one IG1240RC3 at the main panel enough, or should I add protection at subpanels too?
The IG1240RC3 is intended as whole home protection at the service, and because it is also Type 2 rated you can install additional units at subpanels feeding sensitive equipment. In multi-unit or light commercial buildings, one at the service entrance plus units at downstream panels is a common layered approach, and the same part covers both positions since it carries both classifications.
8) What is TPMOV technology in this Intermatic surge device?
TPMOV stands for thermally protected metal oxide varistor. The IG1240RC3 uses TPMOV modules, which build the thermal disconnect into the varistor itself so a failing MOV is taken offline rather than overheating in the enclosure. That is why the unit can be installed as a Type 1 device without a separate external overcurrent device.
9) What is the exact part number and manufacturer for this whole-home surge protector?
Intermatic, part number IG1240RC3, from the IG Series of surge protective devices. It is built in Mexico. That MPN is what to quote when matching an existing installation across a portfolio of properties.
