Replacements & Compatible Products
Schneider direct replacements:

LC1N630M7N: Official successor to LC1E series, same economic positioning

LC1D620M7C: Standard contactor, 620A, more stable performance

LC1F630M7: High‑performance series for severe duty

ABB: AF630‑30‑22 (630A, 220V AC)

Siemens: 3RT2076‑6AP36 (630A, 220V AC)

CHINT: CJX2‑630S (630A, 220V AC)

Important Notes
Some LC1E models are discontinued; LC1N series is recommended for new projects
Verify load type (resistive/inductive), operation frequency, and environment during selection
Match thermal relay rating to motor rating (630A typically controls ~315kW motors)

Better Schneider Contactors Than LC1E630M7N

Contactors superior to LC1E630M7N fall into three categories:

Upgrade Replacement (LC1N630M7N / D3N),

Standard Enhanced (LC1D620M7C / LC1D630M7C),

High‑Performance Premium (LC1F630M7 / LC1G630M7).

Recommendation:

New projects → LC1N630M7N

Severe applications → LC1D620/630

Frequent starts / high altitude / special certs → LC1F / LC1G

LC1E630M7N belongs to Schneider EasyPact TVS (economic) series – a domestic 3‑pole contactor, 630A (AC‑3, 440V), coil 220V AC 50/60Hz.

Limitations:

Some ratings discontinued (06A–95A phased out)

Electrical endurance approx. 100,000 operations (AC‑3), lower than standard/high‑performance models

Narrower ambient temperature range; limited special certifications (marine, railway)

2.1 Upgrade Replacement: LC1N630M7N (EasyPact D3N)

Official replacement for LC1E, improved economic version.

Advantage	Improvement
Performance	Electrical endurance ↑ ~20%; mechanical endurance 12 million
Design	More complete modularity, better accessory compatibility
Reliability	Upgraded arc chamber for harsh environments
Installation	Optimized terminals, stable torque, easier maintenance
Compatibility	Same footprint as LC1E for drop‑in replacement

2.2 Standard Enhanced: LC1D620M7C / LC1D630M7C (TeSys D)

Schneider’s mainstream standard series, balanced performance and cost.

Key Benefit	Specification
Higher durability	Electrical endurance 150,000 operations (AC‑3); mechanical 15 million
Wide environment	‑25°C to +70°C; altitude ≤4000m (vs ≤2000m for LC1E)
Special certs	Supports marine (DNV), railway, etc.
Safety features	1NO + 1NC standard; mirror contacts available
Rating range	LC1D620 (620A), LC1D630 (630A)

2.3 High‑Performance Premium: LC1F630M7 (TeSys F) / LC1G630M7 (TeSys Giga)

For severe duty: frequent starts, heavy loads, extreme environments.

Series	Key Advantages	Applications
TeSys F (LC1F)	• Electrical endurance: 200,000 operations (AC‑3)	Metallurgy, mining, large compressors
	• Higher current margin (630A → short‑time 700A)	Frequent operation (≥1200 operations/h)
	• Lower holding power (≈180VA)
TeSys Giga (LC1G)	• Up to 300,000 operations (AC‑3)	Offshore platforms, high altitude (>4000m), ‑40°C
	• Rated insulation voltage 1000V, stronger breaking capacity	Critical high‑reliability equipment
	• IP20 standard, some IP65

Note: k = 1000 operations; M = 1 million operations

Selection Advice
New projects first choice: LC1N630M7N – perfect drop‑in replacement, better performance, affordable
General industrial use: LC1D620M7C – higher reliability for automation and HVAC
Severe duty: LC1F630M7 – frequent starts (>600/h), heavy load, high temperature
Critical/extreme environment: LC1G630M7 – offshore, high altitude, low temperature, maximum reliability
Important Warnings
Although LC1E is not fully discontinued, Schneider officially recommends LC1N for better supply continuity
630A contactors typically control ~315kW (440V) three‑phase motors; match load, duty cycle, and environment
Use matched thermal relays: LRE630N (LC1E/LC1N) or LRD630 (LC1D/LC1F)
