상품 특징

• SPEC & OE CROSS — SPST-NO (1 Form A) power relay with mounting bracket; quick-connect terminals (#187 coil / #187 or #250 load per datasheet). Rated load: 15A resistive at 220VAC or 24VDC; max operating voltage 250VAC/125VDC; TV-5 rating; UL Recognized (File E41643). Contact material: AgCdO. Compatible with part numbers: G4B-112T1-US-DC12/DC24, G4B-112T1-US-AC24/AC100-110/AC120; cross family: G4B-112T-US (0.250 load), G4B-112TP-US (PCB), high-capacity FD variants. Verify coil voltage before ordering.
• OPERATION & INSTALL — Chassis/panel-mount relay for control panels, spa packs, furnace/boiler boards, and HVAC blower/pump/light circuits. Mount via the integral bracket; use 0.187 in female disconnects for coil and 0.187/0.250 in for load per your variant. Wire per the bottom-view diagram in the datasheet; isolate coil from load; add snubber/MOV where required. Typical issues solved: heater/blower not energizing, pump not switching, chatter from worn contacts. Match SPST-NO contact form and coil voltage to the original before power-up.
• COMPATIBILITY SCOPE — This is a general-purpose relay used across multiple industries rather than a vehicle-specific part. For compatibility, match by electrical specs and terminals: SPST-NO, 15A resistive (220VAC/24VDC), max 250VAC/125VDC, quick-connect terminals (#187 coil; #187/#250 load), and coil selection (DC12/DC24/AC24/AC100-110/AC120). Compatible with equipment that originally specifies a G4B-112T1-US-type relay (e.g., many spa/hot-tub and heater controls). Vehicle year/make/model fitment is not applicable for this industrial part.
• REPLACEMENT/ALTERNATIVES — The G4B series is discontinued. Compatible with Omron migration options noted by distributors (e.g., G7L-1A-TUB, LY1F) as conditional replacements. These are not drop-in: verify coil voltage, contact form, footprint, and dimensions before substituting; redesign may be required.
• COMPLEMENTARY ITEMS — Pair with appropriately rated inline fuse holders (ATC/ATO) for load protection, insulated 0.187/0.250 in female quick-disconnect terminals, and heat-resistant mounting hardware. For inductive loads (motors/solenoids), add an MOV or RC snubber across contacts to reduce arcing and extend relay life; keep connections tight and recheck creepage/clearance as per datasheet guidance.
